WHIFFLETREF..

SPECIFICATION forming part of Letters Patent No. 513,054, dated January 16, 1894.

Application led December 1, 1892. Serial No. 453,710. (No model.) v i l To all whom it may concern..-

strong and durable and easily manufactured.'

Figure 1 is an elevation of a blank which forms the top part and the two sides of the structure; Fig. 2, a plan or top lview of the completed article; Fig. 3,.a transverse section on line 3, Fig. 2, looking in the direction inl dicated by the arrow; Fig. 4, a transverse section on line 4, Fig. 2; Fig. 5, a transverse section on line 5, Fig. 2; Fig 6, the part forming v the under side of the structure; and Fig. 7, a transverse section of the same.

Referring to the drawings, A represents a dat blank piece of metal of the outline shown, which forms the top and the back, front sides and closing end naps of the structure.

In the process of manufacture the blank A is first stamped out. The two edges a u. are

next turned at right-angles to the top part a2,

on the broken lines shown. The edge a forms the back, and a the front sides of thecompleted structure. The blank is widest at the center; the back line gradually narrowing in the direction of the respective ends so that the completed whiietree B is of the greatest diameter at the center and gradually tapers Atoward the ends, as shown in Fig. 2. The

flaps as are next turned inwardly to close the ends of the hollow structure, and the bottom plate O placed in position. The center clip b is then slipped over from the end and shrunken into place, as are the quarter-clips b bfor the stay-chains, and the end-clips b2 h2. The center clip is 'also secured by a rivetboltb and is provided with an aperture b4 for the insertion of a king-bolt. The quarterclips are also securedl by a rivet-bolt d, and the end-clips by rivet-bolts d d in each end, thus completing a structure combining strength and lightness,.and firmly banding the parts together. angular form in cross -section, and so arranged as to bring the widest parts edgewise with reference to the line of draft.

Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent, is-

The hollow metallic tree consisting of an integral top, sides and ends formed from a single blank as described, a bottom piece of substantially the same shape as thetop, and binding clips surrounding and tightly embracing the tree body, substantially as described.
